Application led July 19, 1912. Serial No. 710,471.

To all whom it may concern Be it known that I, AUGUST T. MINGE, acitizenwof the United States, residing at Breckinridge, in the county ofGarfield, State of Oklahoma, have invented certain new and usefulImprovements in Plow* shares; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention has special reference to plows and more part-icularly toplowshares, the primary obj-ect of the invention being to provide aplowshare having a simple, novel and durable fastening means by whichthe same is secured to the mold board and land side of the plow withoutthe use of bolts and so that the share can be readily attached andremoved.

With the above and other objects in view, the invention consists ofcertain o-ther combinations and arrangements of parts as will behereinafter more fully described, claimed and illustrated in theaccompanying drawings, in which:

Figure 1 is an underside view showing the parts of the plow separatedand looking toward the edge portions of the mold-board and shareconstituting a part thereof. Fig. 2 is a perspective rear view with theparts assembled. Fig. k3 is a detail perspective view of the shareremoved. Fig. 4 is a similar view of the mold-board and land side withthe share removed.

As illustrated in the drawings, the lnumeral 10 designates themold-board and the numeral 11 the land side which is attached to themold-board by an angular plate or frog 12 having its `forward endreduced in width and tapered as shown at 13 while the free edge of theportion of the frog which is secured to the mold-board is beveled andcurved upwardly as shown at, 14 for engagement with the plowshare aswill be hereinafter described. A brace 15 also connects the rearportions of the land side and moldboard and its free end is tapered andprojects beyond the forward edge of the moldboard as shown at 16.

The share is indicated by t-he numeral 17 and terminates in a point 18and is formed at its forward edge with a triangular pro- ]ecti'o-n 19having a side flange 20 for receiving the projecting portion of the frogand retaining the same from lateral displacement. The inner face of theshare is provided with a curved offset portion or lip 21 which receivesthe curved edge of the frog and further holds the parts coupled togetherandl permits the same to be slid one into the other.

The rear portion of the inner face of the share near its rear edge'i-sprovided with a keeper or bracket 22 which receives the projecting end16 of the brace 15 which is securely held therein by means of a. wedgekey 23 so that the parts are securely held from displacement. Theforward end of the keeper projects upwardly as shown at 24 immediately`in rear of the lip 21 to overlie the mold-board and thus hold the partsof the plow in' positive alinement for proper cutting action.

It will thus be seen that I have provided a very efficient and novelform of plow share and securing means for the two parts of the plowwhich greatly facilitates the attaching and separation thereof for alldesired purposes.

I claim:

1. The combination with a plow having its frog portion extended past themoldvboard and land side, of a detachable share,

alaterally and inwardly bent extension embracing the extended portion ofthe frog, a lateral extension at one side of the frog, an angular flangeon the share for receiving the extension of the frog last-mentioned, anextension carried by the mold board, a bracket for receiving' theextension and means for locking the extension in the bracket.

2. The combination with a mold-board, a landside and an angular platesecured thereto and provided with a reduced pointed forward end, theportion secured to the mold-board having a curved edge; of a bracebetween the mold-board and landside, a. plowshare having a lateraltriangular projection provided With a flange receiving and key engagedbetween the keeper' and brace holding the aforesaid forward end of theto lock the parts together. 10 angular plate, an offset carried by theshare In testimony whereof, I aliix my sigmfor receiving the curved edgeportion of ture, in presence of two witnesses.

the angle plate, a keeper also carried by the AUGUST T. MINGE. lay andhaving an extension engaging the lVitnesses: mold-board to hold theparte in alineinent, C. W. BURTON,
